Self-aligned, gated arrays of individual nanotube and nanowire emitters

We demonstrate the production of integrated-gate nanocathodes which have a single carbon nanotube or silicon nanowire/whisker per gate aperture. The fabrication is based on a technologically scalable, self-alignment process in which a single lithographic step is used to define the gate, insulator, and emitter. The nanotube-based gated nanocathode array has a low turn-on voltage of 25 V and a peak current of 5 μA at 46 V, with a gate current of 10 nA (i.e., 99% transparency). These low operating voltage cathodes are potentially useful as electron sources for field emission displays or miniaturizing electron-based instrumentation.

Individual notions of distributive justice and relative economic status

We present two experiments designed to investigate whether individuals’ notions of distributive justice are associated with their relative (within-society) economic status. Each participant played a specially designed four-person dictator game under one of two treatments, under one initial endowments were earned, under the other they were randomly assigned. The first experiment was conducted in Oxford, United Kingdom, the second in Cape Town, South Africa. In both locations we found that relatively well-off individuals make allocations to others that reflect those others’ initial endowments more when those endowments were earned rather than random; among relatively poor individuals this was not the case.

Subcutaneous fat composition of youthful and mature Canadian beef: emphasis on individual conjugated linoleic acid and trans-18:1 isomers

[EN]A comprehensive evaluation of the fatty acid composition of subcutaneous adipose tissue from beef cattle produced in western Canada was undertaken to determine if the current Canadian grading system is able to distinguish classes of animals with value added potential due to their fatty acid composition. Grades included youthful Canadian Yield Grade 1 A/AA beef, under (YUTM) and over (YOTM) 30 mo of age and the four mature grades (D1, D2, D2 and D4). Subcutaneous fat between the 12th and 13th ribs over the longissimus muscle was obtained from 18_21 animals per grade. Fatty acids were analyzed using a combination of silver-ion HPLC and GC with a highly polar 100 m column. There were no differences in total trans-18:1 content amongst grades, but adipose tissue from grade D1, D2 and D4 had more 11t-18:1 than YUTM (PB0.05), whereas adipose tissue from YUTM carcasses had more 10t-18:1 than all other grades (PB0.05). Adipose tissue from YUTM carcasses also had less total CLA (PB0.05) than the D grades, mainly due to a lower level of 9c,11t-CLA, but they had slightly more 7t,9c-CLA and 10t,12c-CLA (PB0.05). Adipose tissue from YOTM and D grades contained more n-3 fatty acids relative to YUTM (0.56% vs. 0.29%; PB0.05) and lower n-6:n-3 ratios (PB0.05). Overall, older animals (YOTM and D grades) had adipose tissue compositions with higher levels of fatty acids with reported health benefits. Taken together, these higher levels may provide opportunities for value added marketing if regulatory authorities allow claims for their enrichment based on demonstrated health benefits. Higher concentrations of beneficial fatty acids, however, need to be considered within the context of the complete fatty acid profile and it would be important to demonstrate their advantages in the presence of relatively high levels of saturated fatty acids.

A imposição de limites ao exercício da liberdade individual como decorrência imediata da produção de normas de convívio

A coesão de organismos sociais humanos é mantida por meio da imposição de limites ao exercício do livre arbítrio por parte dos indivíduos e das coletividades de indivíduos que os integram e compõem. Esse objetivo é alcançado pela atuação de quatro mecanismos que se influenciam mutuamente: a ética, a moral, o direito e as convenções sociais decorrentes da assimilação de novos conhecimentos. Os limites impostos ao comportamento instituídos no âmbito desses mecanismos serão aplicados tanto ao relacionamento entre indivíduos como ao relacionamento entre comunidades e aos contatos entre estas e aqueles. Tais limites apresentarão algumas características comuns, qualquer que seja o meio onde se desenvolvam: a sensação de legitimidade com que são vistos pelos alcançados; a forma ao mesmo tempo universal e heterogênea por meio da qual se aplicam aos integrantes do meio social em que são estabelecidos; a presença de instrumentos de coerção a eles correlacionados; o caráter dinâmico que faz com que se encontrem em permanente mutação; e o fato de que constituem criações coletivas. Esses limites serão originados de procedimentos específicos para cada período, cultura ou espaço territorial em que se vejam implantados. Não serão permanentemente compatíveis com os valores do meio social no qual são instituídos, mas em todos os casos tenderão a evoluir no sentido de se ajustarem a esses valores. Desse último fenômeno resulta uma estreita vinculação entre o teor de juízos coletivos e o conteúdo dos limites estabelecidos pelo meio social para o comportamento humano, o que acarreta na errônea concepção de que sociedades distintas, por se fundarem em apreciações valorativas igualmente discrepantes, não apresentam traços em comum. Demonstrar que essa última conclusão se afasta da realidade, a partir da premissa de que em qualquer meio social se busca o estabelecimento de limites ao comportamento humano, constitui o objetivo central do presente estudo.

Variation in size of yellowfin tuna (Thunnus albacares) within individual purse-seine sets

ENGLISH:Length-frequency samples of yellowfin tuna from 276 individual purse-seine sets were examined. Evidence of schooling by size is presented. Yellowfin schooled with skipjack are smaller and more homogeneous in length than are yellowfin from pure schools. Yellowfin in schools associated with porpoise appear to be more variable in size than yellowfin from other types of schools. No relationship was found between the tonnage of yellowfin in a school and the mean length of the yellowfin. Despite the tendency to school by size, the size variation within individual schools was judged to be enough to complicate greatly any program of regulation aimed at maximizing the yield-per-recruit through increasing the minimum size of yellowfin at first capture. SPANISH: Fueron examinadas las muestras frecuencia-longitud de atún aleta amarilla, de 276 lances individuales de redes de cerco. Se presenta la evidencia de agrupación por tamaños. Los atunes aleta amarilla agrupados con barrilete, son más pequeños y más homogéneos en longitud, que los atunes aleta amarilla de cardúmenes puros. El atún aleta amarilla en cardúmenes asociados con delfines parece ser más variable en tamaño, que el atún aleta amarilla proveniente de otros tipos de cardúmenes. No se encontró relac¡'ón entre el tonelaje del atún aleta amarilla en un cardumen y la longitud media de esta especie. A pesar de la tendencia a agruparse por tamaño, se juzgó, que la variación de tamaño en cardúmenes individuales, sería suficiente para complicar grandemente cualquier programa de reglamentación, dirigido a obtener el máximo del rendimiento por recluta a través del incremento del tamaño mínimo del atún aleta amarilla en la primera captura.

Behavioral profile of adults with Prader-Willi syndrome : correlations with individual and environmental variables

Background: Maladaptive behavior has been reported as a phenotypical feature in Prader–Willi syndrome (PWS). It severely limits social adaptation and the quality of life of children and adults with the syndrome. Different factors have been linked with the intensity and form of these behavioral disturbances but there is no consensus about the cause. Consequently, there is still controversy regarding management strategies and there is a need for new data. Methods: The behavior of 100 adults with PWS attending a dedicated center was assessed using the Developmental Behavior Checklist for Adults (DBC-A) and the PWS-specific Hyperphagia Questionnaire. The DBC-A was completed separately by trained caregivers at the center and relatives or caregivers in a natural setting. Genotype, gender, age, degree of obesity and cognitive impairment were analyzed as variables with a hypothetical influence on behavioral features. Results: Patients showed a relatively high rate of behavioral disturbances other than hyperphagia. Disruptive and social relating were the highest scoring DBC-A subscales whereas anxiety/antisocial and self-absorbed were the lowest. When hospital caregiver and natural caregiver scores were compared, scores for the latter were higher for all subscales except for disruptive and anxiety/antisocial. These effects of institutional management were underlined. In the DBC-A, 22 items have descriptive indications of PWS behavior and were used for further comparisons and correlation analysis. In contrast to previous reports, rates of disturbed behavior were lower in patients with a deletion genotype. However, the behavioral profile was similar for both genotypes. No differences were found in any measurement when comparing type I and type II deletions. The other analyzed variables showed little relevance. Conclusions: Significant rates of behavioral disorders were highlighted and their typology described in a large cohort of adults with PWS. The deletion genotype was related to a lower severity of symptoms. Some major behavioral problems, such as hyperphagia, may be well controlled if living circumstances are adapted to the specific requirements of individuals with PWS.

Plan De Cuidados Estandarizado. Atención individual a personas con úlcera venosa

Se presenta un Plan de Atención de Enfermería en Atención Primaria para personas que presenten úlceras venosas en las extremidades inferiores, y que frecuentemente, se oye como motivo de consulta: “Sensación de pesadez y calambres en las piernas que va en aumento al final del día”. Las úlceras venosas siendo con diferencia, el tipo de úlceras más frecuentes de la extremidad inferior, suponen un importante problema de salud, tanto para las personas que las padecen, consecuencia del largo tiempo que precisan hasta su curación, como para los sistemas sanitarios que requieren una gran inversión en recursos humanos y materiales. Para tratarlas, es necesaria la implicación y participación de la persona en el proceso de cuidados, como receptor y eje central del mismo, además de la puesta en marcha de estrategias dirigidas hacia la continuidad de cuidados. Se utiliza, el modelo conceptual de Virginia Henderson (la persona como un todo e independiente) y como metodología enfermera para la gestión y planificación de los cuidados, el Proceso de Atención de Enfermería mediante un lenguaje universal y estandarizado a través de la interrelación de las taxonomías NANDA I - NOC - NIC. La enfermera interviene supliendo o acompañando a la persona, cuando observe la insatisfacción de alguna de las 14 necesidades humanas básicas propuestas por V. Henderson en su modelo, proporcionando cuidados integrales y orientando la actuación hacia el logro de su independencia para llevar a cabo sus autocuidados.

The relative abundances of Sn, Te, Xe, Ba, and Ce in the cosmic radiation

Elements with even atomic number (Z) in the interval 50 ≤ Z ≤ 58 have been resolved in the cosmic radiation using the Heavy Nuclei Experiment on the HEAO-3 satellite. Their relative abundances have been compared with the results expected from pure r-process material, pure s-process material, and solar system material, both with and without a modification due to possible first ionization potential effects. Such effects may be the result of the preferential acceleration, and hence enhancement in the cosmic rays, or those elements having low first ionization potentials. We find that our measurements are inconsistent with pure r-process material at the greater than 98% confidence level whether or not the first ionization potential adjustments are made.

In addition, we have compared our results with mixtures having varying ratios of pure r-process material to pure s-process material. We find that, if no first ionization potential effects are included,

(r/s)CRS/(r/s)SS = 0.20^+0.18_-0.14

where CRS refers to the cosmic ray source and SS refers to the solar system, consistent with having an almost pure s-process source. If the first ionization potential adjustments are applied

(r/s)CRS/(r/s)SS = 1.5^+1.1_-0.7

consistent with a solar system mixture.
